He mentioned having Ethernet ports throughout his house. I believe the blue ones are Ethernet cables. A few of them indicate 5e and 350 MHz, confirming they are Cat 5e. I found five of them!
I planned to charge 150 for setting up three mesh routers, removing the wires and linking them to a switch. I also needed a second switch that would connect to three separate Ethernet ports inside the house, all using Ethernet.
The alarm uses Cat 5 cable too... Don't jump to conclusions without checking the connections. From the images you shared, it seems similar but I recommend using a tester to verify which lines are connected and labeling them properly. Capture many photos so you can easily correct any mistakes later.
Cat5 is suitable for phone connections regularly. It’s not visually appealing, but it functions. Avoid exhausting all the pairs.
This is a freaking mess. I don't know what is what and if he had security system or not. I am trying to only go once and fix all of this. Especially because of covid. I am going to ask him if he has security system and to take picture of all his ethernet ports thru the house. And what not. I repost those pics I have until next Monday to figure out how to do all of this. I can definitely use a small switch that only connects the three mesh routes to that switch to lead to back haul ethernet connection. I feel like his is more than 150 dollar job especially after what all of you posted.. I ask him also how many phone lines he has as well.!
Consider this as a 66 block. You don't have all eight Ethernet wires, just two four-wire phone ports. Still, given the messy nature of some tasks, it wouldn't be surprising if someone repurposed this for an Ethernet patch panel—though it shouldn't be used that way. Unfortunately, you'll need a toner or tester to trace these wires back to their source. Plus, there might have been a security alarm before, but it could be disconnected now.
